Blonde bombshell Malin Akerman may be heating up TV screens as a smokin' hot stepmom this fall on "Trophy Wife," but the new mother, who welcomed her son, Sebastian, in April says she's not going to be nearly as cool at home as her character.

Now that she has her own kiddo, she told omg! that she'll be ditching her typically relaxed personality for a strict parenting approach.

"I'm locking those doors; he's never leaving the house," the 35-year-old joked about her plans to keep Sebastian safe. Akerman also dished about how she's adjusting to being a mom, how she dropped her baby weight so fast, her favorite workouts, and her obsession with Muller greek yogurt.
